I maintain a Rust-based CLI HTTP server that embeds Nushell. It’s a handy little Swiss-army knife that’s replaced Nginx and Caddy for my personal projects.

You can serve a folder of static assets like this:

http-nu :3021 '{|req| .static "www" $req.path}'

https://github.com/cablehead/http-nu

I was looking to try something like this (without the nushell...), but I find that I always have caddy installed anyway, and for the really local cases I use php -S.

I'm curious, what do you think is missing from Caddy that has you looking for something new?

I agree. this tool feels like an all-in-one swiss knife. granted, it is useful. But it goes directly against one of the UNIX core values which is "do one thing and do it well". as well, including too much functionality in one single package will eventually bloat it, and there are many examples of this happening (windows, systemd, etc.).

I feel that the applicability of the "do one thing and do it well" philosophy scales with the frequency with which you expect to do that thing and the complexity of the task. In the case of a text editor or a VCS it obviously makes sense. In the case of tools that I use a couple times a year like these, having them all grouped together under a 'misc' application is exactly what I need in order to waste time fumbling through my installed apps trying to remember where I left the QR code generator.

I see this more like `busybox`, where being a single binary is an implementation detail. The commands are still orthogonal and composable.
